how to install hosted-engine without internet connection ?
by tommy 18 Jan '21

18 Jan '21

Hi,every one! My env cannot access internet, but during the hosted-engine installation, It needs to run yum install to update system. I have made a yum source mirror local, but there is a step ( after create engine vm, the vm runs yum update using default repo configure ) it failed to connect yum source. How can I configure yum source to local yum server before the vm run update ? Thanks.

Disaster Recovery using Ansible roles
by Henry lol 17 Jan '21

17 Jan '21

Hi, I have 2 questions about Disaster Recovery with Ansible. 1) regarding Ansible failover, AFAIK, a mapping file must be generated before running failover. then, should I periodically generate a new mapping file to reflect the latest structure of the environment? 2) I guess Ansible failover uses OVF_STOREs to restore the environment and OVF_STOREs in storage domains are updated every 1 min as default. then, how to recover the changes made in the meantime?

Hyperconverged Ceph + Managed Block Storage
by Shantur Rathore 16 Jan '21

16 Jan '21

Hi all, I am planning my new oVirt cluster on Apple hosts. These hosts can only have one disk which I plan to partition and use for hyper converged setup. As this is my first oVirt cluster I need help in understanding a few bits. 1. Is Hyper converged setup possible with Ceph using cinderlib? 2. Can this hyper converged setup be on oVirt Node Next hosts or only Centos? 3. Can I install cinderlib on oVirt Node Next hosts? 4. Are there any pitfalls in such a setup? Thanks for your help Regards, Shantur

potential split-brain after upgrading Gluster version and rebooting one of three storage nodes
by user-5138＠yandex.com 15 Jan '21

15 Jan '21

Hello everyone, I'm running an oVirt cluster (4.3.10.4-1.el7) on a bunch of physical nodes with Centos 7.9.2009 and the Hosted Engine is running as a virtual machine on one of these nodes. As for the storage, I'm running GlusterFS 6.7 on three separate physical storage nodes (also Centos 7). Gluster itself has three different volumes of the type "Replicate" or "Distributed-Replicate". I recently updated both the system packages and the GlusterFS version to 6.10 on the first storage node (storage1) and now I'm seeing a potential split-brain situation for one of the three volumes when running "gluster volume heal info": Brick storage1:/data/glusterfs/nvme/brick1/brick Status: Connected Number of entries: 0 Brick storage2:/data/glusterfs/nvme/brick1/brick /c32d664d-69ba-4c3f-8ea1-240133963815/dom_md/ids / /.shard/.remove_me Status: Connected Number of entries: 3 Brick storage3:/data/glusterfs/nvme/brick1/brick /c32d664d-69ba-4c3f-8ea1-240133963815/dom_md/ids / /.shard/.remove_me Status: Connected Number of entries: 3 I checked the hashes and the "dom_md/ids" file has a different md5 on every node. Using the heal on the volume command doesn't do anything and the entries remain. The heal info for the other two volumes shows no entries. The affected gluster volume (type: replicate) is mounted as a Storage Domain using the path "storage1:/nvme" inside of oVirt and is used to store the root partitions of all virtual machines, which were running at the time of the upgrade and reboot of storage1. The volume has three bricks, with one brick being stored on each storage node. For the upgrade process I followed the steps shown at https://docs.gluster.org/en/latest/Upgrade-Guide/generic-upgrade-procedure/. I stopped and killed all gluster related services, upgraded both system and gluster packages and rebooted storage1. Is this a split brain situation and how can I solve this? I would be very grateful for any help. Please let me know if you require any additional information. Best regards

cockpit-ovirt-dashboard
by Gary Pedretty 15 Jan '21

15 Jan '21

So with the latest updates to Ovirt and CentOS 8 Stream it seems that you either can not install cockpit-ovirt-dashboard, or if you do, it downgrades cockpit-bridge and cockpit-system. You then end up not showing up to date on these hosts on Open Virtualization Manager and can only get back to a fully updated datacenter by doing a yum update --allowerasing which then removes cockpit-ovirt-dashboard. My main concern is now that the command line hosted-engine commands have been removed, if the hosted engine is not running for some reason you have no visibility into what is going on since the regular cockpit host interface will not show the virtualization features. You can't put a host in maintenance or start the engine manually. example.... [root@ravn-kvm-1 admin]# yum install cockpit-ovirt-dashboard //////snip/////// Installed products updated.

how does host's status changes ? Especially Unassigned or NonOperational or NonResponsible
by lifuqiong＠sunyainfo.com 15 Jan '21

15 Jan '21

Hi all, I'm confusing in Host's status in Ovirt Eninge. When will the host's status become Unassigned or NonOperational or NonResponsible? and If the host's status change to these statuses, What will ovirt response to it? After reading Ovirt Engine's source code, I find Only HostMonitoring.java and AutoRecoveryManager.java will change the status of Host. for example, If the host's status is changed to NonOperational, The AutoRecoveryManager will traverse the NonOperational hosts and calling ActivateVdsCommand.java, which will only set the Host's status to Unassigned ? But I don't know What's the next step? So where I can find the article or manual or other helpful information about this question? Thank you . Your sincerely Mark
